Sounds like it's a crap shoot, might stay the same, but most likely will go down. Looks like weight is a decent driver too. Thanks guys, guess I might just have to suck it up and do it.

I've gotten as high as 22 and as low as 15. I get the lowest mpg in the winter. I also have bigger tires, no air dam, brush guard, etc. Id say my average, pure highway, driving is 19mpg when it's not winter.

Mine is relatively stock short of a catback and agressive tune.
